T 0 (ZZZ whom it may concern: 7

Be it known that I, BERNHARDT J ORGEN- SEN, a subject of the King ofDenmark, residin at Beverly, inthe county of Essex and tate ofMassachusetts, have invented certain Improvements in Machines. forShaping Uppers to Lasts, of which the following description, inconnection with the back when the upper is carried inwardly over it. Theinvention is herein shown in its application to a pulling-over machineincluding means for lasting the toe portion of the shoe after theupper'pulling operation, but it will be understood that the invention,

in its broader aspects, is not limited to machines for performing bothpulling-over and lastingoperations.

When the parts of a shoe are assembled on a last, theinnersole orthe-sole of the shoe, hereinafter termed generically the sole, isusually attached to the'bottom of the last at a plurality of points bytacks which are driven through the sole and into the last at a distancefrom the margin of the sole. Since the'margin of the sole, to aconsiderable distance inward from the edge of the last, is thus leftunattached, there is danger that the margin may be uplifted from the,last by the frictional engagement of the upper or of the pulling overgrippers with the edge of the sole during the upper pulling operation,or it may 'be by the action of lasting wipers in their positioningmovement relatively to the shoe preparatory to their overwlpingmovement,

and in the subsequent operation of laying or wiping the upper overthesole the margin may consequently be turned back in such manner as toprevent the upper from being properly sewed to the sole. This danger isparticularly marked in the case of turn shoes, since the soles of suchshoes project beyond the edge of the last bottom and are also usuallyreduced inthickness at the margln to provide a shoulderto which theupper 1s to be sewed, leaving between the shoulder and the edge ofthesole a comparatlvely thin portion termed the feather iof the sole.

This invention provides, as an important feature, a novel organizationof mechanism for positioning the margin of a solein relation to alastand for causing said positloning means to be withdrawni'to permit theupper to be shaped .over the margin of the sole. Theillustrativeconstruction provides a hold-down for engaging the margin of the sole atthe toe and means for withdrawing the hold-downinwardly over the sole 1na dlrection lengthwise of the sole. Combined with the toe-hold-down, inthe illustrative machine, are hold-downs for the ma'rgm of the sole at.the sides of the shoe;

bodiedin a machine comprising upper pulling and fastening means, residesin a novel construction and arrangement ofmeans for positioning themargin of the sole. in rela tion to the last during the upper pullingoperation and 'means for withdrawing the positioning means fromthemargin of the sole to pe'rmit'the operation of the fastening means.As applied to amachine of the'illustrative type, wherein upper pullingand other operations are efiected in different periods or stages of thecycle of movements of themachine, the invention provides, as a furtherfeature, a novel construction and arrangement 'ofpositioningmeans' forengaging the margin of the sole during the upper pulling operation andmechanlsm for effecting a withdrawal of 'sald positlonlng means 1n alater period of the cycle.

' ,The various features ofthe inventiom including certain more importantdetails of construction and combinations of parts, will now be describedwith reference .to' the ach companying drawings and pointed out'in theclaims. I I In the drawings,

Fig. 4 is a view similar to Fig. 3, showing the toe hold-down retracted,and

Fig. 5 shows in detail a portion of the mechanism for controllingmovement of the toe hold-down.

The drawings illustrate the application of the invention to a pullingover and lasting machine of a well known type particularly adapted foroperation upon turn shoes,

described herein in detail.

The machine has the usual toe gripper 2 and side grippers 4:, thesegrippers being operated to pull the shoe upper over the last throughtheaction of updraw levers 6 and 8 to which the respective toe and sidegrippers are connected. The machine has also a front tacker arm 10 andside tacker arms 12 carrying instrumentalities of the usual constructionfor laying the upper over the margin of the sole after the upper pullingoperation and for fastening the margin of the upper in position on thesole, the front tacker arm in the construction shown carrying wipers 14;which are mounted to swing laterally of the shoe and operated by theinward movementof the front and side tacker arms to wipe the upper intolasted position around the toe end of the shoe. Itwill be understoodthat the operation of the machine is effected in successive stages, themachine coming to rest at the end of the first stage with the upperunder tension to afford opportunity for inspection of the work and, ifnecessary, adjustment of the upper to position it correctly withreference to the sole and the last, as well as adjustment of the tensionunder which the upper is held. l/Vhen the machine is started a secondtime, it causes side clamp arms 16 to swing inward and clamp the shoefirmly at the sides,

these arms being operated by means of a slide 18 to which movement isimparted by a cam 20 on the main cam shaft 22. If the operation of themachine is effected in three stages, the machine will again come to astop after the clamp arms have moved into engagement with the shoe, andat this time the operator positions the wipers 14: in engagement withthe toe end of the shoe in the correct relation to the shoe for movementinward to wipe the upper over the margin of the sole. The toe gripper isthen released from the upper, whereupon the gripper is automaticallylifted out of the way of the wipers and the tacking mechanism by theusual spring in the gripper operating connections. When the machine isstarted the third time the front and side tacker arms are swung inwardlyto overlay the margin of the upper and to wipe it into lasted positionaround the toe and fasten it, substantially in the manner explained insaid prior Ashton patent, the grippers receiving simultaneously aninward movement over the sole whereby they make way for the inward 0movement of the overlaying and fastening devices and the side grippers.also serving by such inward movement to overdraw the margin of theupper. During the continued operation of the machine in the final stageof its cycle of operations the parts are all restored to their initialpositions. It will be understood that if the operation of the machine iseffected in two stages only, the wipers will be positioned in engagementwith the upper immediately following the upper tensioning movement ofthe grippers, and the inward movement of the clamp arms 16 will befollowed immediately by the overlaying and the fastening of the upper inthe final stage. While the invention in its broader aspects is notlimited with respect to the precise number of stops which the machinemay make, certain advantages follow the use of the invention in amachine which makes one stop only, the cycle of opto rock the carrierabout the shaft 26 in a direction to hold the roll 80 in engagement withthe cam. Pivoted on the lower side of the carrier 24 for swingingmovement in substantially parallel relation to the plane of the sole area pair of arms 34 which are normally held by a spring 36 with theirfront ends projecting outwardly as well as forwardly in such position asto be opposed to the margin of the sole at the opposite sides of a shoewhen the shoeis presented to the machine. The margin of the sole atinward pressure of the overlaying wipers and swing inward against thetension of the spring 36. A spring plate 38 is secured t0 the head ofthe machine and arranged to bear frictionally upon the rear ends of thearms 34, the pressure of the spring upon the arms beingincreased by thedownward rocking movement of .the carrier 24 which takes place, asusual, during the upper tensioning movement of the grippers. The purposeof the spring plate 38 is to hold the arms 34 with their front endsswung inward until after the side grippers have been returned tostarting position in the finalQstage of the cycle of operations of themachine, thus preventing the grippers from striking the arms. When theholder 24 returns to its starting position the pressure of the spring 38on the arms is decreased sufiiciently to permit the arms to be swungoutward substantially into engagement .with the side grippers by theaction of the spring 36.

The means including the arms, 34, herein shown, for positioning themargin of the sole at the sides of the shoe is more fully described andis claimed in a co-pending application of Orrell Ashton, Serial No.129,214, filed on November2, 1916, and assigned to the assignee' of thepresent invention.

For carrying out the objects ofthis in- I vention the machine shown isprovided further with a. hold-down for engaging and positioning themargin of the sole at the toe endo'f the shoe. This 'hold-down'comprisesa plate 40 curved in substantial conformity to-the edge contour of thetoe end of the sole and shaped to provide a depending lip for engagementwith the feather a of the sole outside of the upper attaching shoulder.The plate 40 is secured to a holder 42 which is pivoted at 44 on a slide46 mounted in the carrier 24 for movement lengthwise of the shoe. Aspring 48 tends to swing the front end of the holder 42 upwardly and ascrew 50 which is adjustable in the holder and is arranged to engage theslide 46 serves to determine the elevation of the hold-down 40 withreference to the slide 46 and the arms 34. i

slide 46 insuch manner as to retract'the impart movement 'to'the shaft26in a dia lug on the'slide 46 and a lug on the'carrier' of the gripperjaws, as shown in Fig. 2, and the hold-down remains in engagement withthe'feather of the sole and, in the case of a turn shoe, with thatportion of the feather which projects beyond the edge of the last,

permit the w1pers14 to lay the'upper over tened,means is provided foroperating the? hold-down from thetoe end of the shoe.

Tothis" end, the slide 46 is providedwith rack teeth 52 which are enaged by a pinion 54 fast on the shaft 26.

6n one endof the shaft 26is a crank arm 56 provided with a ondxcrank arm68 connected by a link 70 j to'the slide-18' which serves, ashereinbefore "explained, to operate theside clamp arms '16. Movement ofthe slide 18 toward the right Fig's 1 and-'2) to'cause the clamp arms tobe closed against the shoe at the beginning of the second period ofthecycle of operations'of the machinethus "serves to rection to retract thehold-down. 40 from 'the' position in which it is shown in Fig. 3 to 'theposition indicated by Fig.4, this movement being effected against thetension of' a spring 72 which ispositioned between 24 and tends tomovethe slide forwardly. The downwardly curving lip of the hold down 40, asshown in Figs. 3 and4, is flared outwardlyon its lower face to permitthe hold-down to. slide readily over the shoulder of the sole in itsretractive movement. With the hold-down thus retracted, the wiping andtacking instrumentalities are permitted to move inward over the marginof the sole and to perform their functions in the usual manner withoutinterference' by the holdf down.

i In view of the close relation between the hold-down 40 and the toegripper jaws 1n the normal shoe receiving position of the parts, it isdesirable that the gripper jaws, after the operation ofthe machine upona shoe, shall return to their starting position prior to the return ofthe hold-down 40 to its foremost position'in' order to avoid danger ofinterference between the gripper jaws and the hold-down. Means isaccordingly provided for maintaining the holddown in its retractedposition for a time subsequent to the returnmovement of the slide 18whereby the clamp arms are caused to release the shoe. To this end, aratchet f .74 is mounted ,uponsone end of the shaft 26 and a pawl 76 isnormally heldlby a spring;

78 in position to engage the ratchet and thus'130 70 until after theupper has been tensioned by the'operatio n; of the grippers.- Inorde'rto to hold the shaft 26 in the position to which it is moved bythe operation'of the slide 18 for retracting the hold-down. The slot andpin connection between the crank arm 56 and the link 62, will thuspermit the return movement of the slide 18 while the holddown iscontinued in its retracted position by the action of the pawl 7 6 on theratchet .7 1. ,After the toe grippers have been re turned substantiallyto their starting .posi tion in the final stage of the cycle ofoperations, an upwardly extending arm 80 of the pawl 76. is engaged by atripping member 82 to cause the pawl to release the ratchet 74 and thuspermit the return of the holddown 40 which is effected by the action ofthe spring 72, hereinbefore described, supplemented by the action of aspring 84: which encircles the shaft 26 close to the ratchet 74 andtends to turn the shaft in the direction to move the hold-downforwardly. Conveniently the tripping member 82 is carried by a slide 85with which machines of the illustrative type are provided for thepurpose of imparting advancing and retracting movement to the heel rest86 of the machine,the retracting movement of the heel .rest taking placeat a time sufiiciently late in the cycle of operations. to permit theuse of the slide for operating the tripping member inthe manner abovedescribed. As the hold-down is returned to its foremost position by theaction of the springs, the pin 58 engages the link 62 at one end of theslot 60 to limit the forward movement of the holddown. A turnbuckle 88is provided for varying the effective length of the link 62, and by thismeans the limit of the forward movement of the hold-down may be varied.

It will be evident'from the foregoing description that the arms 34 andthe member 40 serve to insure the correct location of the margin of thesole with reference to the last at the sides and the toe end of the shoerespectively, and that these members and the carrier 24 constitute asole rest for the shoe with which the sole is engaged when the shoe ispresented to the machine, the hold-down member 40, moreover, serving todetermine the lengthwise position of the shoe in the machine. With theshoe presented as indicated in Fig. 2 and the margin of the upperpositioned within the jaws of the side and toe grippers, the machine isstarted by the actuation of the usual clutch controlling treadle and thegrippers are thus caused to pull the upper over the last, the carrier24: being rocked simultaneously by the cam 28 in a direction to depressthe last within the upper through the pressure of the members 34: and 40on the sole. The machine having come to a stop with the upper undertension, the operator makes any necessary adjustment of the position ofthe upper on the last and of the tension of the upper in the customarymanner. The operator then releases the toe gripper from engagement withthe upper and positions the wipers 1% in the correct relation to theshoe for closing movement to wipe the upper over the margin of the sole,the toe hold-down remaining in position to prevent any upturning of theedge of the sole by this positioning movement of the wipers. He thenstarts the machine again whereupon the side clamp arms 16 are swunginward, the toe hold-down being simultaneously moved rearwardly, and thearms 10 and 12 are moved'inward to lay the upper over the margin of thesole at the sides of the shoe and to cause the wipers 1 1 to wipe theupper over the sole at the toe end, the tacking instrumentalities beingoperated also to fasten the margin of the upper in position upon thebottom of the sole. During the inward movement of the side arms 12 themembers 34: yield inwardly as hereinbefore explained. Following thetacking of, the shoe, the parts of the machine are returned to theirstarting positions, the return of the toe hold-down 40 being delayed bythe action of the pawl 76 on the ratchet 74: and the return of the sidehold-down members 3 L being also delayed by the action of the springplate 38 on these members, in order to avoid any possibility of injuryto the different hold-down members through engagement of the gripperstherewith during the return of the latter to their starting positions.Finally, the pawl 7 6 is released from the ratchet by the action ofthemember 82 and the hold-down 40 is advanced substantially intoengagement with the toe grippers, the return of the side hold-downs 3 1also being effected by the spring 36 as soon as the pressure of thespring plate 38 there on is relieved by the upward rocking movement ofthe carrier 2 Although the hold-down 10 and its op erating means havebeen described herein as arranged for operation upon the margin of thesole at the toe end of the shoe, it will be understood that theinvention in its broader aspects is not limited in respect to theparticular portion of the margin of the sole which the hold-down isadapted to engage- Having described the invention, what 1 claim as newanddesire to secure by Letters'Patent of the United States is:
